I wrote a small "C" program that parses the headers of an incoming message
and if it believes that a receipt is to be generated, it does.

Then added the shadow entry to the transports file, and used the other
appropriate flags (hint: use the "pipe" transport driver, and set others as
necessary).

Works great.  Thanks much; wish I could share the program but it is, as they
say, a "work for hire".  It shouldn't take much for someone to duplicate
this functionality though.... it was only an hour's worth of hacking.

I'd like to suggest that someone pick this up and include it in the next
smail3 release or patch; it's quite useful.

I am currently setting the return address for the receipts to "postmaster";
that seems appropriate since it's really the postmaster who's doing the
notification.
